Hello everyone I was just looking around and say a major Indian provider Sify (AS9583) is announcing /64s via BGP along with main /32 which is their allocation from APNIC. inet6num: 2001:0E48::/32 netname: SILNET descr: Sify Limited descr: Value Added Network service provider country: IN admin-c: HS51-AP tech-c: HS51-AP status: ALLOCATED PORTABLE mnt-by: APNIC-HM mnt-lower: MAINT-IN-SIFY changed: hm-changed@apnic.net 20040211 changed: hm-changed@apnic.net 20060117 source: APNIC As per IPv6 prefixes announced by AS9583 via bgp.he.net - http://bgp.he.net/AS9583#_prefixes6 we can see multiple /64s. Prefix <http://bgp.he.net/AS9583#>Description <http://bgp.he.net/AS9583#> 2001:0e48::/32 <http://bgp.he.net/net/2001:0e48::/32>Sify Limited [image: India] 2001:0e48:0000:0001::/64 <http://bgp.he.net/net/2001:0e48:0000:0001::/64>Sify Limited [image: India] 2001:0e48:0000:0002::/64 <http://bgp.he.net/net/2001:0e48:0000:0002::/64>Sify Limited [image: India] 2001:0e48:0000:0004::/64 <http://bgp.he.net/net/2001:0e48:0000:0004::/64>Sify Limited [image: India] I see Tata Comm (Sify's upstream) is accepting /64s while Tinet (one of other upstream) is dropping and taking only /32. Other major backbones like HE, Level3 dropping but Telia still accepting. Pretty much mixed result. Is it simply a misconfiguration or there is some use of announcing /64s along with main /32?
